GROSSCUTSAW.

Specification of Letters Patent.

Patented Feb. 9, 1915.

Application filed March 6, 1914. Serial No. 822,947.

To all whom it may concern:

Be it known that 1, ROBERT W. GRAVES, a citizen of Canada, and aresident of Elizabeth, in the county of Union and State of New Jersey,have invented a new and Improved Crosscut-Saw, of which the following isa full, clear, and exact description.

The object of the invention is to provide a new and improved crosscutsaw more especially designed for cross-cutting purposes such asfelling'trees, sawing felled trees into the desired length, sawinglumber and the like, and arranged to allow convenient and quickadjustment of the saw blades for sawing work of different diam eters, tocut the work by two blades from opposite sides and to hold the sawblades with the desired tension in engagement with the work withoutpressure on the part of the operator. In order to accomplish the desiredresult, use is made a pair of spring-pressed crossed handles providedwith adjustable heads carrying saw blades having their teeth oppositeeach other to cut into the work toward each other from opposite sides.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a plan view of the crosscut saw; Fig. 2 is a front edge viewof the same; Fig. 3 is a plan view of the crosscut saw provided with anauxiliary handle; and Fig. 4 is a side elevation of the same.

A pair of handles A and B are attached at their rear ends to thestraight terminals C, C of a coil spring C to swing the ban dles A and Bnormally outward away from each other. The handles A and B are pro videdwith. sidewise extending ends A, B crossing one the other, so that thesaid ends move toward each other by the action of the spring G on thehandles A and B. On the ends A, B are adjustably secured heads D, Dprovided with saw blades E and E having their teeth extending towardeach other so as to cut into a tree, log, lumber or other material fromopposite sides, as plainly indicated in Fig. 1. The heads D and D areadjustably secured to the ends A, B by the use of bolts F passingthrough the said heads and engaging notches A B arranged on the ends Aand B of the handles A and B. By the arrangement described the heads Dand D can be set nearer toward eachother or farther from each other tocorrespondingly hold the saw blades E and E apart when sawing materialsof different diameters. The end A is preferably in the form of a forkforming a guide for the end A so that the saw blades are held in properalinement with a view to cause the two kerfs cut by the saw blades tomeet at the center of the log or other material operated on.

In using the saw, the operator takes hold of the handles A and B andpresses the same toward each other with a view to cause the saw bladesE, E to move outward away from each other with a view to engage theteeth of the two saw blades with the log or other material at oppositesides thereof, as indicated in Fig. 1. The operator then re leases thepressure on the handles to allow the spring to force the teeth of thesaw blades E and E into engagement with the log, tree or other material,and then the operator simply draws the saw forward and backward in theusual mannerto cause the saw blades to cut into the material fromopposite sides thereof. 7

In felling trees it is desirable to cut the tree as close to the groundas possible, and in order to do so conveniently use is made of anauxiliary handle G (see Figs. 3 and 4;) provided at its forward end withsprings H and H terminating in hooks H H engaging the handles A and B toyield with the same. The handle G is also provided with spaced hookbolts 1 hooking onto the coil spring C so as to securely fasten thehandle diametrically to the coil spring C, as will be readily understoodby reference to the drawings. The forward portion G of the handle G ispreferably offset, as plainly indicated in Fig. i, to enable the user totake hold of the handle G a desired distance above the ground forconveniently sawing the tree close to the ground.

The crosscut saw shown and described is very simple in construction andcan be readily manipulated with a view to quickly cut a tree, log orother material to be sawed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A crosscut saw, comprising a pair of handles having sidewiseextending outer crossed ends, a coil spring having its terminalsconnected with the rear ends of the said handles to swing the free outerends of the handles toward each other, heads mounted to slide on thesaid free ends of the said handles, means for adj ustably fastening thesaid heads in place and saw blades attached to the said heads.

2. A crosscut saw, comprising a pair of handles having outer crossedends, a coil spring having straight terminals attached to the rear endsof the said handles to swing the said outer free ends of the saidhandles toward each other, the said free ends having spaced notches,heads held to slide on the said free handle ends, saw blades attached tothe said heads and having their teeth eX- tending toward each other, andbolts engaging the said heads and the said notches to adjustably fastenthe said heads in place on the outer ends of the handles.

3. A crossout saw, comprising a pair of crossed handles, a coil springhaving its terminals connected with the rear ends of the said handles toswing the free outer ends of the handles toward each other, heads heldon the said free ends of the said handles, saw blades attached to thesaid heads, an auxiliary handle having spring arms detachably engagingthe said handles, and hook bolts on the said auxiliary handle removablyengaging said coil spring.

4. A crosscut saw, comprising a pair of handles having outer crossedends, a coil spring having straight terminals attached to the other endsof said handles to swing the free outer ends of the handles toward eachother, heads adjustable on the outer ends of the handles toward and fromeach other, saw blades carried by the said heads, and means forfastening the heads in adjusted position.

5. A crosscut saw, comprising a pair of spring pressed handles havingcrossed ends extending sidewise in opposite directions, the end of one.of said handles being in the form of a fork through which the end of theother handle is guided, and saws held on the free ends of the saidhandles. 7

6. A crosscut saw, comprising a pair 0 handles having outer crossed endsextending in opposite directions and having guided ROBERT WESLEY GRAVES.[n s] Witnesses:
